Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0037] like figure 1 As shown, the hardware structure of the SS7 analysis platform includes two boards: a signaling extraction card and an X86 board. The signaling extraction card includes 16 10GE optical ports, a Gigabit Ethernet port, a control port (corresponding to CONSOLE in the figure), an HDMI port and two USB ports, of which the 1st to 4th ports are used to connect data Source, the 10 ports of 5-14 are reserved for later expansion, and more data sources can be connected during expansion. The 15th 10GE optical port is connected to the first 10GE optical port of the X86 board, and the data of the 1st to 4th ports are switched to the first 10GE optical port of the X86 board in turn. The 16th 10GE optical port is connected to the second 10GE optical port of the X86 card to transmit signaling-related data. The Gigabit Ethernet port is directly connected...

Abstract

The invention discloses a No.7 signaling analysis method and analysis platform based on an x86 board card. According to the method, quick support for various fields of No.7 signaling analysis is realized, and support for different ITUs (International Telecommunication Unit) used for protocols such as ISUP (International Subscriber Identity Protocol) and MTN (Multimedia Transfer Network) is realized by modifying a wireshark source code in combination with the wireshark source code and the type of data encapsulation; according to the method, details of Wreshark source codes for parsing the No.7 signaling are studied, definition understanding of each protocol layer field of the No.7 signaling is combined, a new function is added to support correct data parsing, and meanwhile, the method can also rapidly support parsing of new fields. According to the method, the support of different data encapsulation types is realized by analyzing the data encapsulation, and the corresponding fields are effectively positioned by combining the characteristics of the Wireshark source code and each layer of protocol, so that the analysis of the No.7 signaling is successfully realized, and the support of the details of the inner layer of protocol is realized.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an x86 board-based SS7 analysis method and analysis platform. Background technique [0002] Different operators realize the interconnection and intercommunication of telecommunication services through the No. 7 signaling system. The No. 7 signaling system involves the analysis of multi-layer protocols, including the second functional level of the message transfer part (MTP2, Message Transfer Part Level 2), the third functional level of the message transfer part (MTP3, Message Transfer Part Level 3), and signaling connection Control part (SCCP, Signalling Connection Control Part), transaction processing application part (TCAP, TransactionCapabilities Application Part), mobile application part (MAP, Mobile Application Part), etc. Among them, MAP also includes Global System for Mobile Communications (GSM, Global System for Mobile Communications), Camel and so on.
